The extension of Line 4 south from Mairie de Montrouge received déclaration d'utilité publique in February 2005. Work to build the extension began in 2015, and was planned to open in 2020.[3] During the planning stages of the extension, the station was tentatively called Bagneux. Following a public vote, the station was named after Lucie Aubrac, a member of the French Resistance during World War II.[4]
The station was opened on 13 January 2022 by Prime Minister Jean Castex.[2][5][6] The extension is expected to bring 37,000 new passengers per day.[7][6] The cost of the extension was 406 million euro, split between Ile-de-France Region (60%), the state (25.7%), and the department of Hauts-de-Seine, in which Bagneux is located (14.3%).[6]
Grand Paris Express
In 2011, it was announced that the station will connect to the new Paris Métro Line 15, part of Grand Paris Express.[8] This is planned to open in 2025.[9] There are also plans to build an eco-quarter around the station with over 2,000 new residents, following the completion of the Line 15 station.[6]
The station was designed by LIN (Finn Geipel and Giulia Andi).[10] It is fitted with platform edge doors, as part of the automation of Line 4, planned to be completed by 2022.[7]
The station has been designed by French architect Marc Barani.[13] An artwork by Italian artist Tatiana Trouvé will take inspiration from caves, fossils and troglodytes.[14]
